Hbase is an open-source non-relational distributed database modeled after google's bigtable and written in java. It is developed as part of apache software foundation's apache hadoop project and runs on top of hdfs (hadoop distributed file system) or alluxio, providing bigtable-like capabilities for hadoop.
Hbase is not running as a yarn application, thus it is necessary to recalculate the memory allocated to yarn and its applications, which results in a reduction in overall memory available to yarn if hbase is installed.
Hbase provides low-latency random reads and writes on top of hdfs. In hbase, tables are dynamically distributed by the system whenever they become too large to handle (auto sharding). The simplest and foundational unit of horizontal scalability in hbase is a region.
Apache hbase’s applications include many sectors wherever the need arises to handle large amounts of data, and the use of a nosql database is required. Let us discuss some of the applications of apache hbase in detail in this post.
Note: the term ‘store’ is used for regions to explain the storage structure. Hbase has three major components: the client library, a master server, and region servers.
Much like a typical mapreduce application, hbase applications are written in java, but they also support writing applications in avro, rest, and thrift. In recent times, hbase’s performance has improved a great deal, and it serves several data-driven websites, including facebook’s messaging platform.

Besides, cassandra’s architecture supports both data management and storage, while hbase’s architecture is designed for data management only. By its nature, hbase relies heavily on other technologies, such as hdfs for storage, apache zookeeper for server status management and metadata.
Apache zookeeper is a high-performance, centralized, multi coordination service system for distributed applications, which provides a distributed synchronization and group service to hbase. It directs the focus of users on the application logic despite cluster coordination.
Also hbase uses zookeeper as a distributed coordination service to maintain server state in the cluster.
Static files produced by applications, such as web server log files. Data for batch processing operations is typically stored in a distributed file store that can hold high volumes of large files in various formats.

It came with a feature of random access by using internal hash table to stores data in hdfs files for faster lookups.
High availability and linear scalability are often primary motivators behind the decision to build on hbase. Very often, the application relying on hbase is required to meet these same requirements. Let’s look at how opentsdb achieves these goals through its architectural choices.
The document can also be stored as a binary value, in which case support for medium objects (mobs) can be used if the documents are large. This approach is described in the book architecting hbase applications.

The hbase architecture consists of servers in a master-slave relationship as shown below. Typically, the hbase cluster has one master node, called hmaster and multiple region servers called hregionserver.
Hbase recovers against that by writing to the wal before the write completes. The hbase cluster keeps a wal to record changes as they happen. If hbase goes down, replaying the wal will recover data that was not yet flushed from the memstore to the hfile. Write the hbase command to list the contents and update the column families of a table.
Hbase architecture follows the traditional master slave model where you have a master which takes decisions and one or more slaves which does the real task.
